Accessories for Spring Charged Operation

Automatic closing spring release

This device allows the charged closing springs to be automati-
cally released when the ACB is drawn out.
ANSI or NEMA-compliant ACBs require this option.

Spring charge indicator

This switch can be used to indicate that the closing springs
have been fully charged.
For contact ratings of the switch, see table c- 1 on page 28.

Trip Devices

Continuously-rated shunt trip device
The continuous-rated shunt trip device allows the ACB to be
opened when an external protection relay against overcurrent
or reverse power is activated.
Because of its continuous rating, the device can also be used
to provide an electrical interlock to the ACB.
Continuously rated shunt trip and undervoltage trip can not be
fitted to the same ACB. However, Instantaneously rated shunt
trip can be used together with undervoltage trip with special
specification. Special double opening and closing coils are
available, contact TERASAKI for details.
Capacitor trip device
In conjunction with the continuously-rated shunt trip device,
the capacitor trip device can be used to trip the ACB within a
limited period of 30 sec if a large voltage drop occurs due to an
ac power failure or short-circuit.
When the continuously-rated shunt trip is used with a capacitor
trip device, "a" contact of auxiliary switch of ACB should be
inserted in series, otherwise internal damage may occur.
